Answer:
39.43 for each dog
Step-by-step explanation:
<u>d = 2c (given) </u>
164 c + 23 d = 4140 sub in the above equation for d
164 c + 23<u> (2c)</u> = 4140
210c = 4140
c =19.71
d = 2c = 39.43

She put the y in the same equation ....it was the mistake
She had to put the y in the other equation:
2x+ 22 - 10x = - 2
-8x + 22 = - 2
-8x= -2 - 22
-8x= - 24
x= 3
X=-6 so you have to plug it into x
3(-6)-2
You should get -20
